Which ports are designated ports? Choose three (when there are 5 correct)

[geo_2007b]

Hi,
I have come up to this question, not included here
            A
          1 2
          /  \
        1    1
        B2 -2C 

A is the root bridge and B2 is disabled
which ports are designated ports, choose three
A1
A2
B1
B2
C1
C2
with the exception of B2 all the rest are designated. Am I missing something?
Unless we don't consider root ports as designated ports.
